Abstract: Tumor-Treating Fields elicit a conditional vulnerability to PARP inhibitors (e.g., Olaparib) in certain cancer cells such as non-small cell lung cancer (NSCLC) cell lines. This conditional vulnerability is exploited in a method of killing cancer cells that comprises delivering a PARP inhibitor to the cancer cells and applying an alternating 80-300 kHz electric field to the cancer cells. At least a portion of the applying step is performed simultaneously with at least a portion of the delivering step. In some embodiments, an additional step of treating the cancer cells with a radiation therapy is added to the method. In some embodiments, the frequency of the alternating electric field is between 100 and 200 kHz.

Abstract: A cardiac assist device includes an expandable cup with a pumping chamber having at least one inflow aperture, an outflow nozzle in communication with the chamber, and a volume displacement member inside the chamber. The volume displacement member is cyclically movable between a low-volume state and a high-volume state at a frequency F, wherein a displacement volume of blood Vd is displaced from the chamber through the nozzle during each cycle. When the volume displacement member moves at frequency F, the device increases momentum of blood flowing through the device such that flow rate of blood exiting the nozzle is substantially greater than the frequency F multiplied by the displacement volume Vd. In some embodiments, the volume displacement member includes a balloon having a proximal region that is distanced from an inner wall of the chamber more than a distal region of the balloon when the balloon is fully inflated.

A web of material may extend between the suction port tubes to increase torsional strength of the manifold. There may be two webs of material with each coupled to opposing pairs of four suction port tubes. The vacuum port may be a single vacuum port.
